AUGUST RADElVIAOHER, OF POOATELLO, IDAHO.

CUTLERY-SHARPENING INSTRUMENT.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed October 2'7, 1906. Serial No. 840.909.

To all whom it may concern:

Be it known that I, AUGUST RADEMACHER, a citizen of the United States,residing at Pocatello, in the county of Bannock and State of Idaho, haveinvented new and useful Improvements in Cutlery-Sharpening Instruments,of which the following is a specification.

This invention relates to cutlery sharpening instruments, being designedespecially for use in sharpening razors, and has for its objects toprovide a comparatively simple, inexpensive device of this characterwhich may be readily manipulated, and one in the use of which a keen,smooth edge will be produced on the razor.

With these and other objects in View, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings; there is shown an elevation, partly insection, of an implement embodying the invention.

Referring to the drawings, it will be seen that the implement comprisesa handle 1 and a sharpening blade 2 on which is formed a reducedscrew-threaded shank 3 adapted for threaded engagement with alongitudinal opening in the handle 1 to fix the blade in place thereon.The blade 2, which is to be employed as a finishing tool in theoperation of sharpening razor blades, is, in accordance with theinvention, composed of steel and in the form of a bar or rod ofperfectly circular form in cross section and finished with a highlypolished, smooth surface, the blade being of gradually diminishing taperfrom its ends toward its longitudinal center, as shown, and havingformed at its outer end a substantially oval head or enlargement 4, theinner end of which partakcs of the tapering formation of the adjacentportion of the blade.

In practice, the razor blade having been carried through the initialsteps in the sharpening operation, is finished on the blade 2 in the useof which the razor blade is laid fiat upon and pressed firmly againstthe tapering portion of the sharpening blade and drawn back and forthfrom heel to toe across the latter in a manner which will be readilyunderstood, it being noted that owing to the blade 2 being of thepeculiar form shown the razor blade will, when laid thereupon, contactonly at its back and edge with the surface of the sharpening blade,whereby the latter will act properly in finishing the razor edge. Ls?

Having thus described my invention, what I claim is:

As a new article of manufacture, a cutlery sharpening instrumentcomprising a sharpening blade composed wholly of steel and made of truecircular form in crosssection, said blade being of gradually diminishingtapered form from its ends toward its longitudinal center to form acontinuous concaved face and being provided with a perfectly smoothhighly polished surface.

In testimony whereof, I afiix my signature in presence of two witnesses.

AUGUST RADEMACHER.
